Answer 1

Step-by-step explanation:

$\huge{\underline{\mathtt{\red{ƛ}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}} :) \bold \purple♡$

Sides of triangle a=12cm, b=16cm and c=20cm

s=

2

a+b+c

=

2

12+16+20

=

2

48

=24cm

Using Heron's formula,

Area of a triangle=

s(s−a)(s−b)(s−c)

=

(24−12)(24−16)(24−20)

=

(12)(8)(4)

=

4×3×4×3×4

=4×3×2=24sq.cm

Answer 2

Step-by-step explanation:

If triangle is right angle triangle,

( Diagonal )² = ( one side )² + ( second side )²

( 25 )² = ( 20 )² + ( 15 )²

625 = 400 + 225

625 = 625

Therefore, the triangle is right angle triangle,

then the area of right angle triangle...

Area of Right Angle Triangle

= ½ (Base × Perpendicular)

= ½ ( 20 * 15 )

= ½ ( 300 )

= 150 cm²
